Blizzard published an update to Patch 2.2.0 on the PTR Friday afternoon with tweaks and changes Legendary items, Set Items, and lots of skills. There are some nerfs, mostly to how many procs channeling skills provide to cooldown reduction, re: Natalya's Set and the Ob/Zod ring, but early testers say it's not so bad for non-channeling skills.

The cooldown of Rain of Vengeance is reduced by 1 2 seconds every time you cast a primary skill and by 2 seconds every time you cast or a Hatred spender from the first hit of each cast of a resource-spending attack

You can now increase your Blood Shard cap by achieving a personal best in Solo Greater Rifts

The cap will be increased by 10 shards per Greater Rift level completed

Some changes have been made to the way Pylons spawn in Greater Rifts

Areas in which Keywardens are located now have a boss icon on the Waypoint map

The icon will indicate whether or not the Keywarden has been killed

This is only for level 60+ games
